I have had much the same experience as most of you above.
Fronts wear out quicker than rears despite the rear wheel bias on Q4, presumably due to weight on front axle.
Despite having 4 wheel tracking done, the inner edge on the fronts still wear as per Alfa 159. I was told that the main problem with mine was the incorrect camber, IIRC?
Fronts to backs and visa versa on the same side to equalise "normal" wear and also to get more life out of the tyres due to the inner edge issue.
After doing 8000 miles in my ownership, and I believe the tyres were fairly new when I purchased the car, average depth left is 5mm and now all four tyres have a slight 1cm or so bald patch on inner edge.
So for the above reasons I do rotate the tyres, and I did think that it was a good idea due to the diff wind up, but maybe according to the above information it's not that important?
